Honeywell LG1093AA24 (261A1812P012) UV Flame Sensor for GE Gas Turbine

Product Brief Description

The LG1093AA24, part number 261A1812P012, is a Honeywell ultraviolet flame detector originally designed for GE heavy-duty gas turbine flame monitoring systems. It comes with a built-in 4.9m (16ft) integrated shielded cable. This UV sensor detects ultraviolet radiation emitted by combustion flames, delivering reliable flame presence signal to the turbine control system. It is a critical safety component for GE Frame series gas turbines, built to withstand high temperature, vibration and harsh combustion cabinet environments.

Product Functions

• Detect ultraviolet UV radiation generated by gas or oil combustion flames
• Convert flame UV signal into electrical feedback signal sent to turbine flame amplifier / control system
• Fast flame loss detection to trigger turbine safety trip logic when flame extinguishes unexpectedly
• Resist interference from visible light and infrared heat radiation to minimize false flame alarms
• High temperature and vibration resistance for direct installation on gas turbine combustor housing
• Provide continuous flame status monitoring during turbine startup, load operation and shutdown phases

Application Scenarios

• GE Frame 1,3,5,6,7,9 series gas turbine combustion flame monitoring
• Combined cycle power plant gas turbine safety protection system
• Industrial gas turbine for cogeneration and captive power generation
• Oil & gas on-site power generation turbine units
• Power plant boiler and combustion chamber flame safety supervision
